When it’s time to install or replace a new HVAC system in your home or business, you often face the difficult decision of choosing between a heat pump or conventional air conditioning system. While these systems generally work the same when cooling your home, there are some major differences on the heating side. This post will cover the basic differences between a heat pump and conventional air conditioning system, how they work, and the factors you should consider before purchasing a new system, including price, energy efficiency, and climate. Both of the systems are considered a type of heat pump as they transfer (or pump) heat from inside the structure to the outside to cool inside temperatures. The major difference between the two is that a heat pump can reverse its direction and transfer heat from the outside to raise indoor temperatures by utilizing a reversing valve built into the compressor. A conventional air conditioning system must rely on electric resistant heat strips within the air handler or utilize furnace heat to produce/distribute warm air.

While heat pumps and conventional air conditioners differ, they rely on the same principals to condition inside air temperatures. Both systems utilize a compressor to compress refrigerant contained within the system. Inside the compressor, gas is compressed, causing its temperature to rise significantly. The gas then flows through the condensing coil where it cools to ambient temperature. As the gas enters the evaporator coil—located inside the house—it expands, causing its temperature to rapidly drop and cool the evaporator coil. A fan or blower assembly within the air handler draws air through the cooled evaporator coil to provide conditioned air to the home’s interior. The main difference between the two systems is that a heat pump can reverse the process by switching the function of the evaporator and condenser coils to raise inside temperatures. Choosing between a conventional HVAC system and a heat pump depends on several factors with the most notable being your climate.

Areas of the country subjected to temperatures 40-degrees and lower for extended periods are not ideal for heat pump installation. The reason being is as the temperature drops, heat pumps work harder to maintain desired comfort levels. This results in more energy use, driving up your utility bill. In addition, once the temperature drops below 40-degrees, most heat pump systems lose their heating efficiency and must switch to emergency heat mode, which utilizes electric resistant heat strips that use more electricity.ratings on hvac systems Since heat pump HVAC systems are more energy efficient than conventional air conditioners, purchasing one of these systems may qualify you for a tax incentive or rebate from the federal government, state, or local utility company, which will reduce the overall cost of the system.average cost to fix car air conditioner

To search for rebate and incentive programs in your area, visit the Database of State Incentives for Renewables & Efficiency. DSIRE is the most comprehensive source of information on rebates and incentives that support energy efficiency and renewables in the country. Since the cooling capacities of both a heat pump and conventional air conditioner are about the same, the heating capacity should carry the most weight when choosing one system over the other. ac unit for 5000 square feetConventional air conditioners are less expensive to purchase, maintain, and operate, while heat pumps provide conditioned air more efficiently which reduces monthly energy costs. The coldest regions of the country—those with extended periods below 40-degrees—are better suited with conventional air conditioning supplemented with an alternative heating source. Regions of the country with milder winters are ideal locations for heat pump installation.

While most heat pump systems are only about 5-percent higher than the base cost of conventional air conditioners, you can expect to pay slightly more for heat pump installation. Since heat pumps handle both cooling and heating, they run year round—which shortens their lifespan significantly when compared to a conventional air conditioner which could also lead to higher prices for service contracts through your HVAC contractor and affect the overall warranty due to the wear and tear on the system. It’s best to get an estimate for the cost of a new heat pump or conventional air conditioning system, but it must be noted that parameters specific to your property/jobsite and climate can affect the final cost.

Of course we can’t write about all of the variations in a short blog post, so we’ll take a look at one of the routine inquiries we see at Service Experts Heating & Air Conditioning: what’s the difference between an air An air handler contains the components that move the air throughout your home, called theIt is usually set inside the home and operates with both the heating and cooling components of your HVAC system. If you take a quick look at an air handler, it may closely resemble a furnace. handlers can run with either an air conditioner or a heat pump and contains the indoor coil, used to cool and heat your home depending on which system it’s running with. Here’s what you should know about air handlers: if you’re searching for a conventional

furnace or air conditioner, you’ll likely never need to know what an air handler is because it’s probable you won’t need one. However, if you’re in the market for an electric heat pump, it’s helpful to know that an air handler will probably be a part of your home’s HVAC system. Air conditioners contain the condenser and are traditionally set outside the home. One of the most common confusions with air conditioners is that they cool the existing air in your home. Air conditioners actually pull out heat from inside your home through a host of pieces in your system and expel it outside. The removal of heat is what makes the air feel cool, not the addition of cold air. The warm air inside your home is drawn into the system through return ducts and then go over a refrigerant coil. As the warm air is blown across the cooled coil,Refrigerant lines then carry the heat outside. Now you’re left with cool, comfortable indoor air that you can enjoy on the
